2017-09-07	tcg: Rearrange ldst label tracking	Richard Henderson
	Dispense with TCGBackendData, as it has never been used for more than holding a single pointer. Use a define in the cpu/tcg-target.h to signal requirement for TCGLabelQemuLdst, so that we can drop the no-op tcg-be-null.h stubs. Rename tcg-be-ldst.h to tcg-ldst.inc.c.

2016-02-09	tcg: Respect highwater in tcg_out_tb_finalize	Richard Henderson
	Undo the workaround at b17a6d3390f87620735f7efb03bb1c96682ff449. If there are lots of memory operations in a TB, the slow path code can exceed the highwater reservation. Add a check within the loop.

2015-05-14	tcg: Push merged memop+mmu_idx parameter to softmmu routines	Richard Henderson
	The extra information is not yet used but it is now available. This requires minor changes through all of the tcg backends. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>
2015-03-13	tcg: Use tcg_malloc to allocate TCGLabelQemuLdst	Richard Henderson
	Pre-allocating 640 of them per TB is a waste. Reviewed-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de> Signed-off-by: Richard Henderson <rth@twiddle.net>
2014-09-29	tcg-aarch64: Use 32-bit loads for qemu_ld_i32	Richard Henderson
	The "old" qemu_ld opcode did not specify the size of the result, and so we had to assume full register width. With the new opcodes, we can narrow the result. Signed-off-by: Richard Henderson <rth@twiddle.net>
2014-05-12	tcg: Define tcg_insn_unit for code pointers	Richard Henderson
	To be defined by the tcg backend based on the elemental unit of the ISA. During the transition, allow TCG_TARGET_INSN_UNIT_SIZE to be undefined, which allows us to default tcg_insn_unit to the current uint8_t.

2014-04-18	tcg: Fix warning (1 bit signed bitfield entry) and replace int by bool	Stefan Weil
	Static code analyzers complain about signed bitfields with only a single bit. is_ld is used as a boolean value, so make it bool. ppc64 already used bool for the 2nd argument is_ld of the local function add_qemu_ldst_label. Modify all other TCG targets to do follow this example. Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Richard Henderson <rth@twiddle.net>
